SIGHT FOR FIREARMS.

Specification of Letters Patent.

Patented July 16, 1918.

' Application filed September 20, 1917. Serial No. 192,351.

To all whom it may concern:

Be it known that I, DONEGAN R. WIGGINS, citizen of the United States, residing at Salem, in the county of Marion and State of Oregon, have invented certain new and useful Improvements in Sights for Firearms; and I do declare the following to be a full, clear,- and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates generally to firearms and more particularly to certain new and useful improvements in sights therefor.

The primary object of the invention is to provide a sight having windage and range adjustments and certain improved mechanism for making these adjustments.

Another object of the invention is to provide a sight of this character which can be readily and easily attached to various types and sizes of rifles, and which is provided with a point blank adjustment to compensate for the various sizes of rifles to which it may be attached.

A still further object of the invention is to generally improve upon devices of this character by the provision of a comparatively simple, strong, durable and inexpensive construction, one which will be efficient and reliable in operation, and well adapted to the purposes for which it is designed.

With these and numerous other objects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings in which similar reference characters are used to designate like parts throughout the several views Figure 1 is a side elevation of a conventional form of rifle, showing a device constructed in accordance with this invention applied thereto; I

Fig. 2 is an elevation of the rear end of the sight;

Fig. 3 is an elevation of the front end of the same;

Fig. 4 is a side elevation of the sight, parts being broken away to disclose the mternal arrangements Fig. 5 is a detail sectional view taken on the plane indicated by the line 5-5 of Figs. 2 and 4;

Fig. 6 is a perspective view of the base of the sight; and,

Fig. 7 is a detail sectional view taken on the plane indicated by the line 7-7 of Fig. 2.

Referring more particularly to the drawing, the numeral 1 designates as a whole the base of the sight. This preferably comprises a metallic block having its upper end enlarged in thickness and concaved as at 2 to adapt it to conform to the curvature of the right-hand side of the rifle. The block 1 is provided with an undercut guide-way or slot 3 on its outer side to slidably receive the sight limb to be hereinafter described. Although the base 1 can be attached to the side of the rifle in any suitable manner, yet it is preferable to secure it to the same by means of a pair of screws 4. These screws 1 extend through the block on each side of the guide-way 3, the holes 5 through which said screws pass being countersunk a considerable distance in the block as clearly shown by the drawings.

lVhile it is not absolutely necessary, yet it is preferable to provide the outer side of the block 1 with a cover plate 6. This is secured in place by means of a number of screws 7.

Threaded into the upper end of the base 1 is a point blank adjusting screw 8, and a range indicator screw 8. The manner in which these screws are used will be hereinafter described.

The reference numeral 9 designates the sight limb, and as shown by the drawings it consists of a vertical portion 10 which is of T-shaped construction in cross section to adapt it to fit and slide in the guide-way 3, and a horizontal arm 11 which carries the sight proper. The vertical portion 10 of the sight limb and the arm 11 are formed integrally with each other, the upper end of the portion 10 joining the arm 11 at the right hand end of the latter.

The sight proper consists of a small plate or lug 12 provided with a peep opening 13 and a square-shaped sleeve 14 at its lower end which is slidably mounted upon the arm 11, the latter being square-shaped as clearly shown in Fig. 7 of the drawings. The sight proper is moved longitudinally upon the arm 11 by means of a screw 15, the latter having threaded connection with the sight proper while it is prevented from moving longitudinally with respect to the sight limb by means of a small set screw 16 which extends through a lug 17 projecting from the sight limb and has its inner end disposed in an annular groove formed in the screw. By engaging the head of the screw 15 and turning the same in either direction, the sight proper may be moved to the right or left. The free end of the arm 11 is provided with a head 18 to limit the movement of the sight proper in one direction.

As clearly shown by Fig. 2, especially, of the drawing, the inner side of the vertical portion 10 of the sight limb is provided with a longitudinally extending groove or recess 19 having its ends terminating in shoulders spaced inwardly from the ends of the portion 10. This recess 19 receives one end of a screw 20 which extends into a threaded recess 20 in the base 1 to prevent the sight limb from sliding all the way out of the guideway 3. The screw is preferably placed in this position by inserting it through an opening 19 which extends through the vertical portion 10 of the sight limb adjacent its lower end, it being obvious that the sight limb must be raised until the opening 19 is brought into alinement with the recess 20' while this is being done. By this construc tion it is only necessary to remove the cover plate 6 and screw 20 in order to remove the sight limb from the base.

The front edge of what may be termed the head of the vertical portion 10 of the sight limb is provided with a series of teeth or notches 21. These teeth or notches 21 are adapted to be engaged by the inner end of a pin 22 carried at the free end of a resilient strip 23. As shown by Fig. 4 the strip 23 is secured at its other end in a recess formed in the front of the block 1, and the pin 22 extends rearwardly from the free end of the strip 23 and through an opening formed in the block. .It is to be understood that the pin 22 is normally and in fact all the time in engagement with the teeth 21.

The rear edgeof the head of the vertical portion 10 of the sight limb is provided with graduations 24;. These graduations are selected according to the various ranges which the rifle is to be shot, and cooperate with a range indicator screw 8 threaded to the base 1.

After the device has been attached to the rifle in the manner above described, the screw 8 is adjusted until the sight is set at point blank, and the screw 8 is similarly adjusted. These adjustments are obviously diflerent with the various makes and sizes of rifles. After these screws are set, it is only necessary to slide the sight limb vertically within the guide-way 3 when the sight is to be set at any particular range, the graduations being read over the top of the screw 8'. The pin 22 will hold the sight limb in its vertically adjusted position, but will permit it to be moved upwardly or downwardly when a slight pressure is applied to the same.

The sight proper may be adjusted horizontally or laterally with respect to the barrel of the rifle by turning the screw 15. Obviously this adjustment is made to compensate for the wind, and this adjustment may be determined by means of a series of graduations which are placed on the rear side of the horizontal portion 11 of the sight limb.

It will be seen that the device may be readily and easily attached to a rifle without first having to specially adapt the rifle for the same. It may be attached to rifles of different makes and sizes inasmuch as it is provided with a point blank adjustment.

From the foregoing, taken in connection with the accompanying drawings, the construction, use and operation of the device will be readily understood without a more extended explanation.

As various changes in form, proportion, and in the minor details of construction may be resorted to without departing from the spirit of this invention, it is to be understood that I do not wish to be limited to the construction herein shown and described other than as claimed.

I claim:

1. A gun sight comprising a base, means for securing said base to any one of a plurality of guns of various kinds and sizes, a sight-carrying device mounted for vertical adjustment on said base and provided with avertical series of graduations, and a vertically adjustable range indicating element on said base and adapted to register with the said graduations.
